Evaluate the following expression.
\[2^3\]
2*2*2
\[2^8\]
the exponents represent how many times we should multiply the base by itself
2*2*2*2*2*2*2
2^8 = multiply 2 by 2 (8 times) \[2*2*2*2*2*2*2*2 \] is not same as 2^3
Oh blah, i got it wrong it's \[\frac{ 1 }{ 8 }\]
then the question is \[2^{-3}\] ??
there is only reason you can flip the fraction (negative exponents) \[\frac{2^{-3}}{1}= \frac{1}{2^3}\]
Oh /:
by the way \[2^{-3}\] is same as \[\frac{ 2^{-3} }{ 1 }\] and yes if the answer is 1/8 then the question should be 2 to the negative 3rd power
Thanks, at first i kinda got confused
easy way to deal with negative exponents change the place and sign if the `negative exponent` is in the denominator move that to the numerator and change sign |dw:1461815248800:dw|
